Abstract

Quality assurance of electrical energy requires an integrated approach to the design and selection of filtering and balancing device. An analysis revealed that the formation of the current filter is performed by the algorithm, based on the power theory laid. In the course of a computer simulation found that the use of the theory of power by Fryze‘s in threephase systems, it is advisable, but in need of correction. By using the methods of electrical engineering theory and modern standards to determine the components of the power correction algorithm is proposed to determine the specified current active power filter. This additional component, are determined by the voltage and current equivalent to a direct sequence and phase angle between them. Modeling power active filter with the proposed changes in the management system proved the efficiency of the proposed solutions. As a result, it proposed to carry out the formation of the active power filter using current theory Fryze and introduction instead of the average values of active power per phase, active power direct sequence, as determined in accordance with the provisions of the standard IEEE 1459-2010
